STAND.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed April 2,1906. Serial No. 309,356.

To all whom. it may concern:

.Be it known that l, HENRY C. CHAMBEELIN, a citizen ol' the United States, and a resident of Olyphant, in the county ol' Lackawanna and State ol' Pennsylvania, have invented a new and Improved Stand, oi"- which the following is a full, clear, and exact description.

My invention relates to staxuls,.such, `for instance, as are used for supporting boilers and analogous members in connection with heating stoves and furnaces.

My invention relates more particularly to a type of stand used in households lor supporting a vertical boiler ol the type commonly used in connection with the ordinary range or cooking stove.

Among the several objects of my invention are the following'.

1. To enable the stand to be readily assembled or taken apart.

2. To render certain parts oi the stand readily interchangeable, so that supporting rings of different sizes maybe used in connection with the same stand for supporting boilers of different diameters.

.lo avoid the use of bolts, screws and other transient [astenings ior the purpose of holding the parts together.

fl. To render the construction exceedingly simple, yet compact and strong.

Reference is to be had to the accompanying draw-` ings forming a part ol' this specification, in which similar characters oi reference indicate corresponding parts in all the views.

Figure l is a side elevation showing the stand assembled and ready for use; Fig. 2 is a horizontal section upon the line 2 2 oi Fig. l, looking in, the direction of the arrow and showing the slip joints lor connecting the suplrorting ring with the fork to the stand; Fig. 3 is an enlarged fragmentary inverted plan showing the under central portion of the base and the manner oi fitting the tubular stein thereinto; Fig. 4 is an enlarged fragmentary section through the upper part of the base and the lower end of the tubular stem; Fig. 5 is an inverted plan ol' one ol' the supportingT rings to be mounted uponv the fork and used as a rest i'or the boiler; and Fig. an. inverted plan ol a larger ring made to lit upon the same fork, the difference between this ring and the one shown in Fig. 5, being that the portions l5, 1 7 are ol' dill'erent diameters.

At 7 is shown a base made preferably of metal, usually cast iron. This base is provided with spiral [ianges 8, the inner edges of which at the points Stare a little further away from the center than the edges are at the points 8|. This part of the construction is quite simple, the arrangemnt being practically that the two integral portions 8 ofthe base 7 are tapered slightly, so as to present relatively to the center a cam-like comiormity, as indicated more particularly in Fig. 3. The flanges 8 are separated by notches 9, disposed oppositely as shown.

A tubular stem 10 is provided with radially projected lobes 11 disposed opposite each other, these lobes being integral with the stem. The stem 10 is iurther provided with an annular bead l2 disposed externally thereon, and located a short distance irom the lower end of the stem. In order to secure the stem 1 0 to the base 7, the lower end of the stem is moved downwardly so that the lobes 1 1 pass through the notches 9. The stem 10 is now given a twist relatively to the base 7, so that the lobes ll move around under the flanges 8, and thus lock the stem iirmly in position, as indicated in Figs. 3 and ll. ln order to remove the stem, it is simply turned in the opposite direction relatively to the base, so that the lobes 11 may pass upwardly through the notches 9, being, of course, first brought into registry.

Connected permanently with the stem l0 are two arms 13 constituting a fork, as will be understood from Fig. 1. The upper ends ofthe arms 13 are oi such conformity as to present the cross section indicated in Fig. 2; that is to say, the cross section oi each arm is substantially equivalent to that of two triangular prisms 1li with their apexes connected integrally together. A supporting ring is shown at 15, and is provided at its bottom with lugs 1G each of the general triangular form shown in Fig. 5, but tapering in diameter so as to afford a maximum o strength combined with neatness, as will be understood from Figs. 1 and 2. To mount the ring 15 upon the fork, the ring is placed upon fork, the plane of the ring being horizontal. The ring is now lowered and forced into position so that the prisnioidal lugs 16 engage opposite sides of the prismoidal arms 14 and adhere thereto with more or less firmness. The ring 15 is shown in Fig. 5, as disconnected from the fork.

In Fig. G a ring 17 is provided with projections 18 extending radially toward the center, each oi these projections beingl provided with prismoidal lugs 19 each having a triangular cross section, the two lugs being disposed with their apexes toward each other. The ring 17 shown in Fig. 6 is exactly like the ring 15 shown in Fig. 5, with 'the exception that the ring 17 is of greater diameter, which is compensated completely by the fact that the projections 18 extend inwardly to such a distance that the lugs 19 register precisely with the upper ends oi the iorli. Bylthis arrangement, the rings oi different diameters are rendered interchange able, so that the same fork, the same stem and the same base may be employed for any number of rings oi differont diameters. This being 'the case, the same stand can be used to support boilers of various diameters by merely changing the rings l5 or 17 to suit the boiler.

It will be noted that by the construction above described, no bolts, screws or other analogous fastenings a cross section equal to that of two triangulaiprisnis with their apexes joined to form V-shaped channels between the adjacent sides oi' the prisms, and a riiu,y provided with downwardly projecting lugs, each 0i' said lugs having :l cross section o1' the general iorin of a triangle, said lugs beingl in pairs, and seated in said channels.

In testimony whereof I have signed niy name t0 this specification in the presence ot' two subscribing witnesses.

HENRY C. CHAMBERLIN.
